[Python-apps-team] Bug#534764: mayavi2: GLXBadContext when creating new scene

[Kevin Mitchell]

Package: mayavi2
Version: 3.2.0-3
Severity: normal


I run

ipython -wthread

and at the prompt the following commands

from enthought.mayavi import mlab,api
mlab.test_surf()

upon which I see
"""
The program 'python' received an X Window System error.
This probably reflects a bug in the program.
The error was 'GLXBadContext'.
  (Details: serial 63 error_code 154 request_code 143 minor_code 5)
...
"""
and I'm dumped back to the command prompt

I've found that one workaround is to manually start the engine first:

from enthought.mayavi import mlab,api
api.Engine().start()
mlab.test_surf()

will give me a working figure.

This workaround does not however work for the OffScreenEngine:

from enthought.mayavi import mlab,api
api.OffScreenEngine().start()
mlab.test_surf()

will give me the same error message as above and dump me to the prompt.

This is a regression from 2.2.0-1 in Lenny.
It occurs with mayavi2=3.2.0-3 but keeping Lenny versions of

libgl1-mesa-dri=7.0.3-7
libgl1-mesa-glx=7.0.3-7
x11-common=1:7.3+18
xserver-xorg=1:7.3+18
xserver-xorg-core=2:1.4.2-10.lenny1
xserver-xorg-video-intel=2:2.3.2-2+lenny6

as well as with the sid packages

x11-common=1:7.3+18
xserver-xorg=1:7.3+18
xserver-xorg-core=2:1.4.2-10.lenny1
xserver-xorg-video-intel=2:2.3.2-2+lenny6

kernel mode setting is not enabled in either case.
